Found the problem.  I guess it (mythweb?) won't generate thumbnails
for recordings made on a different machine.  Since I was changing
machines, I had changed the hostname of my master backend, so only the
recordings made on the new master backend had non-zero-byte thumbnails
generated.

For future reference, here is the SQL command I issued:

UPDATE recorded
SET hostname = 'newservername.domain.com'
WHERE starttime < 'date-of-move'

So in my case, my first recording was made on the new server on
2008-08-29, so all recordings prior to that had the old server name.
Thus, my date-of-move was 2008-08-29 in my SQL query.

Hope that helps anyone else.
